Abstract
In this work, a 70/140 GHz dual-band push-push voltage controlled oscillator(VCO) has been developed based on a 0.18-${\mu}m$ SiGe BiCMOS technology. The lower band and the upper band oscillation frequency varied from 67.9 GHz to 76.9 GHz and from 134.3 GHz to 154.5 GHz, respectively, with tuning voltage swept from 0.2 to 2 V. The calibrated maximum output power for each band was -0.55 dBm and -15.45 dBm. The VCO draws DC current of 18 mA from 4 V supply.
